[0050] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0051] Magnetic resonance equipment consists of magnets and magnet power supplies that generate magnetic fields, gradient field coils and gradient field power supplies, radio frequency transmitters / receivers, system control and data processing computers, imaging operation and image analysis workbenches, and mobile examination beds. Magnetic resonance equipment uses the characteristics of atomic nucleus spin motion to generate signals in an external magnetic field after being excited by radio frequency pulses. The signals are detected by detectors and input into computers. After processing and conversion, the medical images are displayed on the screen, which can be used to diagnose tumors, inflammation, vascular lesions, infections, and other lesions.
[0052] The inside of the magnetic resonance device has an aperture. After the patient lies on the operating table, he or she can be pushed into the inside of the aperture. After the magnetic resonance device scans the human body, it can be converted into a scanned image and displayed on the display device. Therefore, the magnetic resonance device can be used in conjunction with an interventional puncture robot. Under the guidance of the real-time image formed by the scanning of the magnetic resonance device, interventional puncture surgery can be performed accurately and efficiently.
[0053] Since the aperture of the magnetic resonance device is small and the length of the aperture is large, and the imaging area with the highest quality of magnetic resonance imaging is located at the center of the aperture depth direction, the existing puncture robot with multiple joints can only perform surgery on the disease in one part due to the limitation of the aperture. For diseases in different locations, different puncture robots need to be designed for coordinated puncture, and the design cost and equipment cost are both high. In order to overcome the above technical problems, the utility model provides a new magnetic resonance interventional puncture device and a magnetic resonance system.
[0054] The magnetic resonance interventional puncture device provided in the embodiment of the utility model is now described.

[0056] The bed 1 is for a human body to lie on. Specifically, during a puncture operation, the human body lies on the bed 1. When the human body lies on the bed 1, the area of the bed 1 corresponding to the head of the human body is the head of the bed 1, and the area of the bed 1 corresponding to the chest and abdomen of the human body is the chest and abdomen of the bed 1. The shape and outline of the bed 1 are generally similar to those of an ordinary bed.
[0057] See also Figure 5 The puncture mechanism 5 includes a frame structure 51, a posture adjustment mechanism 52 and a puncture terminal 53. When the puncture mechanism 5 is installed on the mobile module, the frame structure 51 is connected to the mobile module. The posture adjustment mechanism 52 is slidably connected to the frame structure 51. When the posture adjustment mechanism 52 slides relative to the frame structure 51, the position of the puncture terminal 53 relative to the frame structure 51 can be adjusted so that the puncture terminal 53 is close to the part to be punctured. At the same time, the posture adjustment mechanism 52 is used to adjust the posture of the puncture terminal 53, that is, to adjust the puncture angle of the puncture terminal 53. One end of the puncture terminal 53 has a puncture degree of freedom, and the puncture action can be performed after its position and posture are determined.
[0058] The magnetic resonance interventional puncture device 100 in the above embodiment includes a bed 1, a mobile module and a puncture mechanism 5, and the mobile module can be installed at different parts of the bed 1. For example, when it is necessary to puncture the chest and abdomen, the mobile module is installed at the chest and abdomen of the bed 1, and the puncture mechanism 5 is installed on the mobile module; when it is necessary to puncture the head, the mobile module is installed at the head of the bed 1, and the puncture mechanism 5 is installed on the mobile module. In this way, the puncture mechanism 5 is suitable for puncture of the head, chest and abdomen, etc., so that the design cost and the device cost can be reduced. In addition, the mobile module can adjust the position of the puncture mechanism 5 relative to the bed 1. The puncture mechanism 5 includes a frame structure 51, a posture adjustment mechanism 52 and a puncture end 53, and the posture adjustment mechanism 52 can adjust the posture of the puncture end 53. By adjusting the position of the puncture mechanism 5 by the mobile module and adjusting the posture of the puncture end 53 by the posture adjustment mechanism 52, it can be ensured that the puncture end 53 is punctured at a preset position and a preset puncture angle.

When the first module 3 is installed on the chest and abdomen of the bed 1 and the puncture mechanism 5 is installed on the first module 3, the position of the puncture mechanism 5 can be adjusted by the first module 3 so that the puncture mechanism 5 is directly facing the puncture site.
[0060] Specifically, when puncture of the chest and abdomen is required, the first module 3 is installed on the chest and abdomen of the bed 1, and then the puncture mechanism 5 is installed on the first module 3. The position of the puncture mechanism 5 is adjusted by the first module 3, and the position of the posture adjustment mechanism 52 and the puncture end 53 relative to the frame structure 51 is adjusted. Finally, the puncture angle of the puncture end 53 is adjusted by the posture adjustment mechanism 52. After the position and puncture angle of the puncture end 53 are adjusted, the puncture end 53 performs puncture.
[0061] The first module 3 includes a first base 31 and a horizontal moving assembly 32, and the first base 31, the horizontal moving assembly 32 and the puncture mechanism 5 can be connected in sequence. The horizontal moving assembly 32 is slidably connected to the first base 31, and the puncture mechanism 5 is slidably connected to the horizontal moving assembly 32.

The first direction, the second direction and the third direction are arranged vertically in pairs. Therefore, in this embodiment, the position of the puncture mechanism 5 in three directions can be adjusted by setting the first base 31 and the horizontal moving assembly 32, that is, the puncture mechanism 5 can be moved to any position within the range, which can basically cover the puncture area corresponding to the thoracic and abdominal cavities.

The receiving cavity is provided at the side of the first base 31 near the bed 1, so that the horizontal moving assembly 32 can be close to the side of the bed 1. When the puncture mechanism 5 is installed on the horizontal moving assembly 32, the puncture mechanism 5 is also close to the side of the bed 1, which is convenient for the puncture mechanism 5 to puncture the chest and abdomen of the human body, and at the same time does not occupy the space where the human body lies. A shielding structure 33 is provided at the opening of the receiving cavity. The shielding structure 33 is used to shield the opening of the receiving cavity, and at least can shield part of the horizontal moving assembly 32 to avoid the exposure of the mechanism inside the receiving cavity.

The horizontal slider 321 slides along the first direction relative to the first base 31 to adjust the left and right position of the puncture mechanism 5 relative to the bed 1. The first frame base 322 slides along the second direction relative to the horizontal slider 321 to adjust the front and rear position of the puncture mechanism 5 relative to the bed 1. The frame structure 51 slides along the third direction relative to the first frame base 322 to adjust the height position of the puncture mechanism 5.
[0070] In some embodiments, the bottom of the horizontal sliding block 321 extends into the interior of the accommodating cavity and is slidably connected to the first base 31 .
[0071] In some embodiments, a first slide rail having a length parallel to the first direction is provided at the bottom of the horizontal slider 321, and a first slide groove is provided on the first base 31.

Optionally, the horizontal slider 321 is in a long strip shape, and the length direction of the horizontal slider 321 is parallel to the second direction, so that the volume of the horizontal slider 321 can be reduced.
[0073] In some embodiments, a third slide groove 512 is opened on the side wall of the frame structure 51, and a third slide rail is arranged on the first frame base 322. The length directions of the third slide groove 512 and the third slide rail are both in the third direction. Through the cooperation of the third slide groove 512 and the third slide rail, the frame structure 51 can slide relative to the first frame base 322 in the third direction.

In this way, the frame structure 51 and the first frame base 322 have at least two connection parts, and the sliding of the puncture mechanism 5 relative to the first frame base 322 is more stable.

The connection between the horizontal moving assembly 32 and the puncture mechanism 5 and the nearby structure can be called the structure to be isolated. Specifically, the structure to be isolated includes at least part of the frame structure 51 and the horizontal moving assembly 32. The baffle 34 is used to isolate the chest and abdomen of the human body from the structure to be isolated, so as to protect the chest and abdomen of the human body, limit the chest and abdomen of the human body, and prevent the human body from touching the above-mentioned structure to be isolated.
